Abstract

Antenna designs are influenced by a range of matters, such as the region of label operation (near or far), the coupling field (electric field or magnetic field), the regulatory constraints and the environment in which they operate. Typically antennas used in the high frequency (HF) band RFID operate at 13.56 MHz whose frequency has an electromagnetic wavelength of around 22 m giving a near-field far-field boundary of around 3.5 m. A common practice of using a magnetic field-sensitive HF antenna suitable for operation in the HF ISM band (13.56 MHz).The label is designed to have a sufficient number of turns to provide the resonating inductance for the microcircuit input capacitance, as well as a flux collecting area in the interior, which is as large as practicable and consistent with the size requirement for the label. This paper presents a design method to optimize the RFID magnetic field sensitive antenna design with an EM simulation program Sonnet Lite manufactured by Sonnet Software Inc. The Sonnet Lite simulator program is very well known program for antenna design. A well designed RFID antenna can effectively reduce the system cost and improve the radio wave broadcast. Apart from that, communication range between tag and reader can be improved. In this project we have designed an antenna, where design has been done and verified its performance by simulation.
